TECHNICAL FIELD

The present disclosure relates to shoelace tying devices and methods. More particularly, the disclosure discusses securely tying shoelaces in a manner which enables a person to establish and maintain desired shoelace tightness.

BACKGROUND OF THE INVENTION

A shoelace used to tie a shoe can become loose and/or untied. This can create safety, comfort, and efficiency problems for the shoe. Furthermore, many people lack the physical dexterity to properly tie shoelaces. Hence, there is a need for an alternative shoelace tying device and method.

SUMMARY OF THE INVENTION

In one embodiment, a device for tying a shoelace comprises: a bobbin with two ports, wherein the ports are configured to accept and firmly hold the two ends of a shoelace; a frame which comprises a bottom portion on which the bobbin rests, a top portion configured with an opening to secure the bobbin and allow the bobbin to rotate, and two supporting members which connect the top portion to the bottom portion, wherein each member includes a port configured to accept a shoelace; and a ratchet which is attached to the bobbin, configured to rotate with the bobbin, and rests atop the frame.

The bobbin with two ports can be cylindrical and is able to rotate to collect a shoelace around its axis.

The frame is configured to enable a user to access a shoelace, secure the shoelace ends to the bobbin ports, and adjust the shoelace around the bobbin axis if required. The frame is configured to rest upon the upper surface of the tongue of a shoe.

The ratchet comprises a gear and a pawl. The gear portion is attached to the bobbin and rotates with the bobbin. The pawl can be spring loaded or can exist as a switch embodiment. The switch embodiment enables a user to freely turn the gear when open and locks the gear when closed. The spring loaded embodiment enables rotation in one direction unless the pawl is physically held open, in which case rotation in both directions is allowed.

In a separate embodiment, the device further comprises shoelace docking means. The shoelace docking means consists of a metallic portion with two shoelace tunnels, the tunnels configured to accept and hold two different ends of a shoelace, and a magnet embedded within the frame bottom portion.

In a separate embodiment, the device further comprises a customizable relief design button.

In a separate embodiment, the device further comprises a beaded chain leash.

The method to use a shoelace tying device to tie a shoelace with aglets comprises: placing the shoelace tying device on a tongue of a shoe between the last two eyelets of the shoe which are laced, wherein the shoelace tying device comprises: a bobbin with two ports, wherein the ports are configured to accept and firmly hold the two ends of a shoelace; a frame which comprises a bottom portion on which the bobbin rests, a top portion configured with an opening to secure the bobbin and allow the bobbin to rotate, and two supporting members which connect the top portion to the bottom portion, wherein each member includes a port configured to accept a shoelace; and a ratchet which is attached to the bobbin, configured to rotate with the bobbin, and rests atop the frame; feeding each shoelace aglet into a corresponding support port and bobbin port; and rotating the ratchet until a desired shoelace tension is achieved.

DETAILED DESCRIPTION OF THE INVENTION

U.S. Pat. No. 8,353,088, awarded to Ha, describes a shoelace tightening device. The Ha device comprises a rotation member, bobbin, and housing. The Ha device must be affixed to a shoe instead of resting freely upon the shoe. The Ha housing does not enable free access to the shoelace after it has been wound around the bobbin. The Ha switch must be held open to enable a shoelace to be unwound. The Ha device also incorporates an elastic tension means to maintain rotation member tension, which creates a potential failure point for the device.

The device of the present disclosure overcomes the limitations of Ha. Specifically, the device of the present disclosure does not need to be affixed to the shoe, a user has access to the shoelace since a frame is used instead of a housing enclosure, and elastic tension means for the rotation member is not used.

The method steps required to tie and untie a shoelace are listed below.

Tying

1. String-up the laces of the shoe evenly, so that their ends are the exactly same length when finished.

2. Once the shoe is on, tighten up the laces to your desired tension (check and adjust laces if they are not the same length when finished with this step).

3. Move the lock control switch 214 on the shoelace tying device 101 to the position where “ON” is covered by the switch and “OFF” is visible.

4. Place the shoelace tying device 101 on top of the shoe's tongue in-between the last two strung-up laces.

5. While holding the frame 203 of the device 101 with 1 hand, use your other hand to take one aglet (i.e. plastic shoestring end) and feed it through the frame member port 209 on the side of the shoelace tying device 101.

6. Once through the frame member port 209, insert the aglet into one of the bobbin ports 208 on the bobbin 201. (The bobbin 201 can be rotated slightly to allow the aglets to be inserted into the bobbin ports 208 easier).

7. Repeat steps 5 & 6 on the opposite side of the shoelace tying device 101 for the 2^(nd) shoestring. (Note: the other aglet should be entered through the bobbin port 208 on the opposite side of where the 1^(st) aglet was inserted)

8. Turn the tension dial column 215 knob to position the bobbin ports 208 in a way that the aglets align straight across from one frame member port 209 to the opposite frame member port 209. This may require lightly pulling some of the slack from one or both laces feeding into the frame member ports 209. (Note: If either of the aglets are pulled out of the frame member ports 209 during this step, reinsert the aglet and repeat this step)

9. Once both ends are anchored to the bobbin 201, move the lock control switch 214 on the shoelace tying device 101 to the position where “OFF” is covered by the switch and “ON” is visible.

10. For shorter laces (3 to 5 inches), use one hand to hold the device 101 in place on the shoe's tongue and use the other hand to turn the tension dial column 215 knob clockwise to tighten up the laces to your desired tension.

-   -   11a. For longer laces, once step 9 is completed. Give the         tension dial column 215 knob a ¼ to ½ turn clockwise to secure         the laces in the shoelace tying device 101.     -   11b. With one hand; lift the device 101 up above the shoe's         tongue until all the slack is removed from the attached laces.         Now, while holding the device 101 parallel to the shoe's tongue;         use the other hand to turn the tension dial column 215 knob         clockwise . . . while slowly lowering the device 101 down into         place on the shoe's tongue. Once the device 101 can rest on the         shoe's tongue, continue to turn the knob clockwise until the         laces reach your desired tension.

Untying

1. Move the lock control switch 214 on the shoelace tying device 101 to the position where “ON” is covered by the switch and “OFF” is visible.

2. Using one hand, with the index finger and thumb . . . grip the device frame 203 right below the tension dial column 215 knob and lightly pull up and towards the toes (at a 45 degree angle). Strings should unwind from the bobbin 201 and detach from the device 101.
